Well I called Costco Concierge services and they had me run through a few mandatory steps to see if it fixed the high pitched squeal. It didn't so they connected me to Vizio's customer service department and they are going to send out a tech to fix it on Thursday 12/15/2011. I'll update what happens after that.
On another note, I'd really like to see what settings someone with the proper equipment uses to calibrate the screen. Perhaps it's because of the edge lit nature of the set, but I find that if I turn off the advance features (excluding the motion smoothing, which is just a matter of taste - I personally hate it and turn it off) that the picture looks significantly worse, and it seems like a struggle to properly compensate using just the typical, Contrast, Color, Tint, etc controls.
What have others done to calibrate the TV?
